WARNING
Danger of explosion due to reduced heat dissipation for places of install-
ation >2000m above sea level.
Death or serious injury.
à When exceeding the value, please contact the manufacturer, since load and isola-
tion restrictions prevail for constant ambient temperature.

Types of duty for different versions
It is imperative to heed the types of duty even if the running times per valve cycle
(OPEN and CLOSED) exceed the limited operating times. The type of duty depends
upon the temperature range on the actuator name plate. Type of duty S2-xx min
(short-time duty) for multi-turn actuators and S4-xx % (periodic intermittent duty with
influence on starting procedure) for modulating actuators are to be considered.
With S2 duty rating, the maximum operating time of the actuator is indicated. Once
this time has expired, the actuator has to pause until it has cooled down to ambient
temperature +2Kelvin. In S4 type of duty, the on time value indicates the permitted
running time with reference to the switching cycle. A switching cycle is defined as time
between actuator start and next start (sum of actuator running time and pause time).
